Kate McKinnon showed up as Ruth Bader Ginsburg at the RNC

Well, that's not someone we expected to see at the Republican National Convention: Kate McKinnon, dressed as Ruth Bader Ginsburg, showed up in Cleveland.

The Saturday Night Live cast member and Ghostbusters star made a surprise appearance on the special Weekend Update show that aired live early Thursday morning on MSNBC. Co-hosts Colin Jost and Michael Che invited her onto the last few minutes of the segment to address the justice's recent remarks on Donald Trump.

"Trump picked a fight with the wrong 200-year-old marionette, baby," said McKinnon-as-Ginsburg, while shadowboxing. "You know, I've been doing CrossFit," she told Jost. "That's when I cross my arms and legs and try to fit inside a soup can."

The justice proceeded to "Ginsburn" politicians, and do elaborate victory dances. It was a hilarious juxtaposition: McKinnon gyrating wildly right in front of the Quicken Loans Arena stage, where the GOP convention speeches are given.

"I don't know how much time I have, Colin, I gotta get my pokes in when I have a chance," she said.
